Medical devices
The biocompatibility, chemical resistance and dimensional stability of PBT make it a suitable material:
Surgical Instruments: Used in handles and components of surgical tools.
Orthopedic implants: Ensures long-term reliability and performance.
Plumbing and fluid handling
PBT's resistance to chemicals and low moisture absorption make it an ideal material:
Valves and Fittings: Used in plumbing systems for reliable performance.
Pump Impellers: Ensures durability in fluid handling applications.
Food processing
Food handling equipment: Components such as fresh datasetconveyor belts and blades for the food industry benefit from the properties of PBT.
Packaging Machinery: Ensures hygienic and efficient operation.
Modification of polybutylene terephthalate
Fiberglass reinforcement
The addition of glass fibers to PBT improves its tensile strength and flexural properties, making it suitable for high-stress applications such as automotive and industrial machinery components.
Flame retardant additives
PBT can be modified with flame retardant additives to meet safety standards in applications where fire resistance is critical. This modification is common in electrical and electronic components.
Polymer blend
Mixing PBT with other polymers such as polycarbonate (PC) or acrylonitrile butadiene styrene (ABS) makes it possible to create materials with suitable properties:
PBT/PC Blends: Combines the chemical resistance of PBT with the impact and heat resistance of PC.
PBT/ABS Blends: They offer a balance between strength, toughness and cost-effectiveness.
Impact modified PBT
Impact modified PBT incorporates impact modifiers to improve its toughness and resistance to impact and shock. This modification is particularly useful in applications requiring high durability and impact resistance, such as automotive interiors and sports equipment.
